Abstract:

Water tanks are the storage containers for storing water. Elevated water tanks are constructed in order to provide required head so that water will flow under the influence of the gravity, the construction practice of water tanks is as old as civilized man. The water tanks project have a great priority as it serves drinking water for huge population from major metropolitan cities to the small population living in towns and villages.Large capacity elevated Intze tanks are used to store a variety of liquids, e.g. water for drinking and fire,fighting, petroleum, chemicals, and liquefied natural gas. A water tank is used to store to tide over the daily requirements. Intze tank is a type of elevated water tank supported on staging. Intze tank is defined as bottom portion of circular tank is provided in flat shape, so in flat bottom, the thickness and reinforcement is found to be heavy.Design and analysis of elevated intze water tank both manually and by using SAP2000 software.The present work deals with the design of elevated INTZE type water tank with 12m diameter with a storage capacity of 1000m3. Usually water tank domes are designed as per the code IS 3370-1987 in working stress method and the staging (columns and beams) is designed as per IS 456-2000 in limit state method. The reinforcement details of for this proposed INTZE type overhead water tank is given and the structure is analysed for basic wind load. In addition the elevated intze tank (reinforced concrete) is designed and analysed for wind by using SAP2000software.Wind analysis of reinforced concrete Intze tank is carried out at different staging heights of tank by assuming to be located in different wind zones in India of different terrain categories. Different parameters like wind forces, displacements due to wind forces at different heights of water tank, area of steel etc., are compared in different wind zones.
